I have never written anything that meant more to me than the message of this book. When I was eighteen, I surrendered to God's call to vocational ministry. Some years later, God spoke to my heart and said something like this: “I sent my Son to set the captives free. You will go forth and ring the liberty bell.” Sweet thought. Even a little poetic for a romantic like me, but it sounded awfully evangelistic. I was fairly certain my calling was in the area of discipleship.
